Does overgrip ruin the original grip of a tennis racquet?

Most good overgrips will not ruin the original grip. Some overgrips have the tendency to stick to the underlying grip, causing extreme damage to the original grip. Other grips will not ruin the original grip.

Really, it is a 'see if it will ruin the grip' kind of thing, because each original grip is different and each overgrip you might use will be different.
